IT 장비 및 기기의 확산과 전력 소비의 증가로 인한 환경문제가 점차 심각한 국제문제로 대두되기 시작하면서, IT 부문의 $CO_2$ 배출과 에너지 절감을 위해 그린 IT의 중요성이 증대되고 있다. 그린 IT는 교육기관에서도 에너지 효율화 및 사교육비 절감 등의 효과를 발휘하기 위해 저탄소 녹색성장을 견인하는 녹색정보화 방향으로 추진되어야 할 필요가 있다. 본 논문에서는 교육기관에서의 녹색정보화를 위해, 학교 구성원들인 교사 학생들이 지켜야 할 그린 IT 사용 지침 및 이를 지속적으로 실천할 수 있는 교육활동을 제안하였다.

Background: Work-related stress is one of the major causes of occupational ill health. In line with the regulatory framework on occupational health and safety (OSH), adequate models for assessing and managing risk need to be identified so as to minimize the impact of this stress not only on workers' health, but also on productivity. Methods: After close analysis of the Italian and European reference regulatory framework and workrelated stress assessment and management models used in some European countries, we adopted the UK Health and Safety Executive's (HSE) Management Standards (MS) approach, adapting it to the Italian context in order to provide a suitable methodological proposal for Italy. Results: We have developed a work-related stress risk assessment strategy, meeting regulatory requirements, now available on a specific web platform that includes software, tutorials, and other tools to assist companies in their assessments. Conclusion: This methodological proposal is new on the Italian work-related stress risk assessment scene. Besides providing an evaluation approach using scientifically validated instruments, it ensures the active participation of occupational health professionals in each company. The assessment tools provided enable companies not only to comply with the law, but also to contribute to a database for monitoring and assessment and give access to a reserved area for data analysis and comparisons.

기존의 사이트와 달리 유네스코는 상대적으로 이미 좋은 이용자 인터페이스를 가지고 있음은 분명하다. 그러나 이용자가 기록물을 활용하면서 지혜롭게 선택 활용하는 이용자 중심형 지식 큐레이팅을 할 수 있는 구조로는 되어 있지 않다. 이용자 개개인이 이러한 혜택을 누릴수 있게 하려면 미리 시스템 측면에서 구조를 달리 표현해야만 가능하다. 현재의 거의 모든 정보시스템은 의미정보, 맥락정보와 함께 우리 마음속에서 만들어지는 생각의 다양한 연결고리를 무시한 채 만들어져 있다. 이용자가 생각함직한 것을 미리 모델링하고 그 모델링을 바탕으로 이용자들이 쉽게 활용할 수 있는 이용자 중심형 인터페이스가 필요하다. 이를 위해서는 시맨틱 기술 기반의 새로운 구조론이 요구된다. 따라서 본 연구에서는 이러한 구조론에 기반한 관계형 패싯 네비게이션이 적용되는 이용자 인터페이스 구현을 위해 이론적이고 실용적인 모델 제안에 이어 프로토타입 수준의 실제 아카이브를 구축해 보았다.

사회기반시설은 국가 경쟁력 지표로써, 전통적으로 정부의 SOC 재정으로 건설되어 왔다. 그러나 SOC 예산 축소에도 불구하고 사회기반시설의 확충 요구를 해결하기 위해 민간투자사업제도가 도입되었으며, 이 중 도로사업의 비중이 높다. 본 연구는 기 제안된 도로사업 사업계획서의 운영관리비와 사업계획서와 연계되는 재무모델의 운영관리비 항목을 분석하고, 도로사업의 특성을 반영하기 위해 한국도로공사의 사업비 항목과 운영관리 업무를 분석하였다. 분석 결과를 통해 분류체계를 마련하여 비용산정 기준을 마련하는 것이 요구된다. 또한 업무의 효율성을 고려하여 기존의 업무 도구를 웹기반으로 통합하여 하나의 시스템으로 개발하는 것을 제안하였다. 이를 통해 민간투자사업의 전체적인 사업성 확보에 기여하고, 수익성을 기반으로 하는 사회기반시설의 확충에 기여할 것으로 기대된다.

Vegetation structure of Seokseong fortress in Buyeo-Gun was investigated to suggest a desirable management proposal. Communities by phytosociological method were classified into Pinus rigida-Pinus densiflora community and Quercus variabilis community. The importance value of Pinus rigida, Pinus densiflora, Quercus variabilis, Pinus thunbergii, and Quercus acutissima were 127.06, 70.29, 69.63, 12.39 and 8.57. According to breast diameter analysis results, it is expected that the importance value of Pinus rigida, Pinus densiflora, and Quercus variabilis will be continuously increased. It should be prepared that vegetation management plan over the castle wall should be considered before the repair or restoration of castle wall. Vegetation management around castle wall should be carried out according to the mid or long-term plan and it would be needed to consider the gradual changes from planted Pinus rigida to the historical vegetation of Pinus densiflora.

Vegetation structure of Sungheung fortress in Buyeo was investigated to suggest a desirable management proposal. Forset communities by phytosociological method were classified into Pinus densiflora community, Quercus serrata community and Quercus aliena community. The importance value of Pinus densiflora, Quercus aliena, Quercus serrata, Quercus variabilis, Castanea crenata, Styrax japonica, Quercus acutissima and Prunus sargentii were 34.81, 13.57, 12.63, 6.73, 6.40, 4.70, 4.54 and 3.65. According to breast diameter analysis results, it is expected that the importance value of Pinus densiflora and Quercus spec. will be continuosly increased. It should be prepared that vegetation management plan over the castle wall should be considered before the repair or restoration of castle wall. Vegetation management around castle wall should be carried out according to the mid or long-term plan and it would be needed to consider the gradual changes from planted Pinus rigida to the historical vegetation of Pinus densiflora.

In a conventional system, hydraulic unit pumps out pressurized oil when the power use is not even necessary. As a result, it causes much power loss. This study is on the proposal of new hydraulic unit which controls the revolution of the pump in order to produce proper power needed and to have good response characteristic. In addition, the existing control methods such as PID control method, fuzzy control method, and adaptive control method are applied to the proposed hydraulic unit. Then the best control method is selected and the controller is developed to realize minimum power loss.

The purpose of this stud)r was to critically review the trends of research methodologies of environmental education. We analyzed Journal of Korean Society for Environmental Education (vol. 1 ∼vol. 14(1)) and The Journal of Environmental Education(vol. 25∼vol. 31) to investigate the trends of methodology in EE research of Korean and other countries and to explore the tasks of it. The findings were as follows, 1) More than half of the character of the papers in Korea were actual condition (54.38%), substitute proposal (32.12%), and the papers in others countries were actual condition (39.35%), substitute proposal (33.55%). 2) The major parts of the method of the papers in Korea were literature review (26.05%), survey research (23.79%), on the other hand the papers in other counties were survey research (42.70%), literature review (25.84%). The results indicated that the research methodologies of environmental education in Korea were needed to be reinforced in the field of qualitative and quantitative research methods.

In the paper, a selection relaying scheme is proposed and analyzed in which relays retransmit the erroneous packet without checking the correctness of their received packets. The proposal not only achieves the full diversity gain in a limited number of retransmissions but it also gets better performance than other schemes. Additionally, a threshold in the number of retransmissions and the closed form expression for packet error rate (PER) are derived. Simulation results are given to confirm the accuracy of analysis and to significantly prove advantages of the proposal.
